Reaction Steps

To a solution of 3-[1-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-ethoxy-N-ethyl-6-methylbenzamide (9.0 mg, 0.017 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (6.6 mg, 0.034 mmol), sodium carbonate (11 mg, 0.10 mmol) in N,N-dimethylformamide (0.1 mL)/water (51 μL) under N2 was added tetrakis(triphenylphosphine)palladium(0) (2.0 mg, 0.0017 mmol). The mixture was heated at 100° C. overnight. After cooling to room temperature, the mixture was filtered and purified on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product (0.9 mg, 10%). The product was isolated as a racemic mixture. LCMS calculated for C22H26ClN8O2 (M+H)+: m/z=469.2; Found: 469.0.
